When is BGA rework better than swapping the entire motherboard?

When the defect is an isolated GPU or PCH joint under thermal cycling and the rest of the rail tree is clean. We X-ray or microsection sample joints, then rework with profiled reflow—Expert cost transparency.

Do you handle 3 V / 5 V always-on shorts after coffee spills?

Yes. We inject safe current limits, use thermal camera gradient mapping, and lift suspect SMD caps on PCH rails until the short clears—Certified tracing discipline.

Can you replace blown MOSFETs in VRM stages without scorching pads?

We use preheat under IR rework, solder paste with correct alloy, and post-repair impedance checks—Guaranteed pad integrity when the laminate is healthy.

Matched FRU-style panels, batteries, and adapters with transparent sourcing—Guaranteed fitment checks before we close the chassis.

Transparent pricing

Written estimates for labour + parts; no surprise add-ons. Certified technicians explain what failed and why.

Liquid ingress along PCH edges often masquerades as “no power.” Our Certified Expert technicians in Coimbatore lift the PCH footprint only after Guaranteed rail isolation—preserving intact SMD clusters.

“As a senior technician at Rajsri IT Services, I always verify 3V3LP before touching RTC domains—Coimbatore humidity loves to bridge under shield cans and fake ‘dead BIOS’ symptoms.”

BGA rework on CPU/GPU packages uses ball-collapse profiles matched to alloy; we log peak temp and soak time for auditability—transparent Rajsri IT Services documentation.

Local context: Fine conductive dust from industrial belts settles under BGA arrays—we ultrasonic clean flux residues and Guarantee post-reflow ICT on critical rails.
